MORALES M., Pamela  y  NOVOA G., Mariela. Morphological description of pelvic limb muscles of a specimen of barn owl (Tyto alba). Rev. investig. vet. Perú [online]. 2021, vol.32, n.5, e21340.  Epub 27-Oct-2021. ISSN 1609-9117.  http://dx.doi.org/10.15381/rivep.v32i5.21340.

The aim of this study was to describe the musculature of the pelvic limbs of a barn owl (Tyto alba). The specimen has powerful muscles, with a predominance in the development of the flexor muscles over the extensors. In general, there is similarity with the musculature described in other birds, especially raptors; however, it is important to highlight some differences, such as m. iliofibular is well developed and is located caudal and superficial to the m. lateral iliotibial; the m. femorotibial has only two heads; the ms. ambiens and fibular long were not observed in the specimen studied, but m. lateral thigh flexor was observed. The m. long digital flexor has only one head; the ms. perforating and perforated are highly fused and m. extensor digitorum longus I has a small muscular head.

Palabras clave : muscles; pelvic limbs; barn owl.
